To all whom t may concern.-

Beit known that I, WILLIAM R. WEBSTER,

\ `a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented av new and useful Drum for Coiling'Metal, of which the follow-l ing is a specification.

This invention has for its object to `produce a drum for coiling sheet metal, wire,rods, 86e.,

which shall be especially adapted for coiling the metal while cold, the essential feature of novelty being that the forward end of the metal to-be coiled forms the connection be-, tween a loose drum and a carrier within it.. With this and other objects in view I have devised the novel coiling-drum which I will now describe, referring to the accompanying drawings,forming a part of this specification, and using reference characters to indicate the several parts.

Figure l is an end elevation,.and Fig. 2 a plan view, illustrating the operation of my i novel coiling-drum in connection with wirerod rolls. Fig. 3 is an elevation, and Figl a longitudinal section, on an enlarged scale,` illustrating one form of -my novel coiling drum. Fig. 5. is a ,cross-section, and Fig. 6a longitudinal section, illustrating another form of my novel ceiling-drum. v Fig'. 7 is an end elevation, partly'broken away, illustrating still another form of my novel coiling-drum; Fig. 8, a section on the line 8 8 in Fig. 7 ;`Fig. 9, a section on the line 9 9 in Fig. 7 Fig.. 10, an elevation of the inner sleeve detached, and Fig. 11 is a longitudinal section of the outer sleeve detached.

20 denotes a rolling-machine as a whole, which will not be described in detail, as it forms no vportion of my resent-invention, which is e ually applicab e `to the coiling of sheet meta as it emerges from the rolls.

2l denotes the drum proper, which is loosely mounted upon a shaft 22, journaled in suitable framework 23. When the drum is used for coiling wire, the wire may be delivered thereto from the drawing-rolls by means of an adjustable delivery-tube 24.

In the forni illustrated in Figs. 1, 2, 3, and 4, which is shown as adapted for coiling wire, the drum 21 may be made tapering and its capacity may be increased to any required extent by the addition of a correspondinglytapering part 25, which is rigidly secured to the sha t, as by a key. 27 denotes an openr not an essential portionof t may be dispensedwith. `The object of part ing in the periphery of the drum, through which the end of wire may be passed. Just within opening 27 is a locking-surface 28,

which in practice is ordinarilyraised and may.

be a detachable block, as shown'in the drawings.-

9 denotes locking-blocks adjustably se-y cured to a carrier 30, inthis form a wheel which lies within the drum and is rigidly secured to the shaft, as by a key. The gripping-surfaces of lockingblocks 29, and locking-surface 28 also,if found desirable, may be corrugated or roughened in any manner to adapt themv to grip the end of metal firmly. Locking-blocks 29 Lare shown as adjustab y secured tothe carrier in order that they may be adjusted to better adapt `them to grip different sizes'of wire or rod.

It should be understood that fixed part 25 of the drum is merely supplemental and is e invention, but

25 is to give greater carrying capacity to the drum, so as to adapt it for large coils of wire Vor rod. For this reason the supplemental portion of the drum is rigidly secured to the shaft.

26 denotes a counterweight which acts to retain the drum, which is loose on the shaft, in such a position that .an end of metal may be conveniently passed into the opening.'

In use, as already stated, the carrier rotates withthe shaft and the drum is loose thereon. An end of wire, rod, or sheet metal to be coiled is passed into opening 27 and iis instantly picked upby oneof the lockingblocks 29 on'the carrier and gripped between said locking-block and the locking-surface 28 on the drum, which is then caused to rotate with the carrier and part 25, the end of metal thus forming the connection between the fixed and loose portions of the structure and the grip upon the metal being so strong that it is practically impossible for it to slip.

In the form illustrated in Figs. 5 and 6 Vthe drum may be made in one piece, or, if preferred, in two pieces, (specifically indicated by 3l and 32,) rigidly secured together, as shown in the drawings. In this form,which is shown as adapted for coiling sheet metal, the drum is cylindrical in form and is provided, as before,with a peripheral opening 27 to receive the end of a strip of sheet metal or a lip projecting therefrom. I Just forward of the'opening is a locking-surface 28, in the present instance a plate, which also serves as IOO IIO

a means for vsecuring thevtwofpar'ts of the drum together, and opposite the lockingblock is a plateio'r cross-piece y35, which also serves to secure the two parts of the drum together. 3 4 denotes counterweights which act to retain the drum', which is loose on the shaft, with the openin in convenient position for the insertion o the end of a strip of sheet metal. c ated by 36) is rigidly secured to the shaft at the mid-len th of thev drum. .37 denotes a locking-bloc on the carrier, which in this form' is pivoted on the carrier'longitudinally thereto and isl cushioned upon aspring or `springs 38, which bear against the carrier belowthe pivot of the block, and thus make the structure self adjusting to varying thicknesses of metal.

The form illustrated in Figs. 7 to 11 inclusive, is equally adapted for coilng wire, rods, or strips of sheet metal. A fixed part, as in Fi 9, may or may not be used, as referrer?. The shaft in this form (indicate b 41)*is made hollow, and the carrier, whic is awheel and indicated by 40, is ri idly secured to the shaft, as by a key. The rum 2l is mounted loosely on asleeve 44, which in turn is ada ted to oscillate on the hollow shaft. 39 enotes a longitudinally-movable rod which lies within the hollow shaftand is yprovided witha radial pin 45, which 'engages la longitudinal slot 46 in the shaft and a spiral is engage by pins56 on va yoke 57, carried by an 'operating lever 58. Longitudinal movement of the rod by means `of the 'operating-lever will cause pin 45 to move along the longitudinal slot in the shaft and the spiral l slot in the sleeve and will Ioscillate the sleeve,

. drum 'will t and conse uei'itly the lockingblocks,on the carrier an cause them to ip or release an end of metal, either wire, rol,F or sheet metal. The counterweights normally hold the drum in such a position that the openingwill conveniently receive an end of metal. of the rod in one direction places the lockingblocks on the carrier in the unlocking or receiving position. When the rod is moved in the opposite direction, said blocks are oscillated and caused to grip an end Aof metal inserted in the opening and passed between one of the locking-blocks on the carrier and the lookin surface on the drum, and the lien be carried forward b v the carrier and the metal coiled thereon. en the rod is again moved in the opposite direction,

and the strips coiled and removed whi e The carrier in this form (indiy A movementV sieno() -eecting an important saving of time, as the ends of the strips of metal may be en aged shaft is in continuous rotation.

Having thus described my invention, I claim- 14. A coiling-drum comprising a loose 'drum having a peripheral opening and a lockingsurfaoe and a rotating carrier within the drum, said parts being so constructed that. the insertion of the end of a piece of metal between them will connect them together and thel drum will be rotated by the carrier and the 'metal coiled thereon.

2. A coiling-drum consisting of a loose drum having a peripheral `o'penin and for- -ward of said opening a locking-sur ace, and a rotating carrier having a coacting lockingblock ada ted t-o grip an end of metal between itsef and the locking-surface on thev drum so that said end of metal will serve as a connection between the carrier and the 'drum and the drum will be carried forward by the carrier and the metal coiled thereon.

'3. A coiling-'drum comprising a loosedrum having a peripheral opening and a lockingsurfa-ce, a rotatable carrier having a pivoted coacting locking-block and means forvoscillatin the lockin'gsblock on the carrier so that it wilgrip or release'an end of metal inserted in the opening.

4. A coiling-drum comprising a loose drum having a peripheral opening anda lockingsurface, a rotatable .carrier having a' pivoted coacting locking-block, an arm extending therefrom, an voscillatory sleeve having an arm extending therefrom, and a link connecting the arm extending from .the sleeve with the 'arm extending from the locking-block on thecarrier, substantially as described, for the purpose spec-ined.

5.
